Thanks for the report - this has been already reported as bug 17376, it is caused by scripts that build the Windows binaries and by now has been fixed in R-patched and R-devel snapshot builds. So as a solution that works now I would recommend using R-patched.

I can confirm the behaviour that you report.

Usually I put Rtools in c:\programs\Rtools and modify the path
accordingly. Recently (don't recall for how long) I have encountered
the same problems as you have and I have resorted to moving Rtools to

I have no idea as how to proceed; perhaps it could be worth trying an
older version of Rtools (though that may cause other problems).

Hi all,

I'm trying to set up the Windows Rtools toolset for building packages
with compiled code. I installed for Windows R-3.4.3 from CRAN and
installed Rtools-3.4 in a custom location M:\R\R-3.4.3 and

Following the instructions, in shell, I set
(the ... are other paths irrelevant for R/Rtools).

When I run

M:\Work\RLibs>R.exe CMD INSTALL --build WGCNA

I get the following ouput:

* installing to library 'M:/R/R-3.4.3/library'
* installing *source* package 'WGCNA' ...
** libs

Apparently the install is looking for Rtools in c:\Rtools. I am a
perpetual Windows newbie and would be really thankful for any
as to how to proceed.
